$CH_3-CH_2-CCl_2-CH_3$

Vedclass · Answer

(B) The iodoform test is given by compounds containing the $CH_3CO-$ group or compounds that can be oxidized to this group. Treatment of $CH_3-CH_2-CCl_2-CH_3$ with aqueous $KOH$ leads to the hydrolysis of the gem-dichloride to a gem-diol $(CH_3-CH_2-C(OH)_2-CH_3)$,which is unstable and loses a water molecule to form butan$-2-$one $(CH_3-CH_2-CO-CH_3)$. Butan$-2-$one contains the $CH_3CO-$ group,which reacts with potassium hypoiodite $(KOI)$ to form iodoform $(CHI_3)$,a yellow precipitate. Thus,the correct compound is $CH_3-CH_2-CCl_2-CH_3$.

Which of the following compounds can give a positive iodoform test when treated with aqueous $KOH$ solution followed by potassium hypoiodite?
